Toallwhomz't man]v concern.:

Be it; known that If, l'alillNV MCGORBX il citizen of the. United States, residing. at:

Karns City, in thecountyv of` Butler State of Pennsylvania, have inventednew and useful llmprovements in Oil-Heaters., offV which they following is; a specification.

This invention an improved; heater.. or steamer, especially adapted for use Oil: fields for heating or steamingpetroleum. an oil tank, the, object;` of the invention loeing tjo provide an improved heatery of this class which is adapted` talee-operated by Ilalv ural gas, which may` be readily set up and taken down, which may be assembled and disassembled and which 'may be. readily connected` to and disconnectedI from` an oil tank, so that the, heater-"mayk be used at different times for steaming or heating oil:V invarious tanks,

specific object of the invention is,l to ef`F` fect improvements in the consti'iiOIl-Oftlie boiler through which the water circulates and in which the water is heated for heatingl or steaming the-oil ina tank.

Another object is to effeot improvements,

in the construction of the` casing'in. which the boiler is arranged.

Another objeet is to Provide the heater with supporting legs which may be readily attached thereto. and; disconnected therefrom and by means of which theY heater may be supported in a vertical position and securely anchored and prevented from being overturned or dislodged. Y Y

Another olojieot ie to eieot improvements,

in the connections between thel heater and the oil tank with which it is used. e

The-invention consists in the. construction, combination and arrangement of devices hereinafter describedandclairned. i

In` the accompanying. drawingstf-Figure 1 is an elevation of an oil heater constructed in accordance with my invention, showing the same set up and connected toz an oil tank and arranged in operative relation thereto for heating or steaming the in the tank,

In accordance with my invention I; provide a cylindrical casing 1,- which is made of plate iron or steel and which is lined with asbestos as at 2 or other refractoryfmaterial.

bur-ners are first; ignited.

'lille bottoini of the casing. is, open, andi` the;

The main` meme,

Each supporting leg has. a bent vertical Lipper end lwhichis adapted tobe inserted and secured in the socket of one of the, blocks` 1,2. The lower ends 17 of the Supporting lege are; ont-turned end arranged horizontally when the4 Supporting legsA ere etteeheel tothe easing The let, horizontal, lower ends efV the supporting legs may bear @ette groen@ orv met be buried therein et eer desired depth in order tormly woher andy secure` the heater in place and prevent it from being overturned orf dislodged, and` to permit` the open end of the casing. to be spaced. a suiicent. distance from a supporting surface with which the legs onthe easing Contact to enable the draft through the casing to, direct the, llames from the burners against the` lower portion of the, boiler tube and` prevents the overheating ofthe oil-in the errer portion ef Said tube when the.

iullcrculatinglboiler n1,8; is arranged in the @eems- Of the heater eed ereoefl from the wallthereof and comprises lower and upper headsA 19.v and 2() and4 vertically arranged tubes 21 which connect the said heads. Each of* the headsishollow andhas three threaded support the boiler in the casing.

openings in which the ends of the tubes 21 are screwed, the tubes being spaced apart 24, the latter providing a union or coupling for the attachment of a pipe 25. A discharge pipe 26 is attached to the upper head 2() and is provided with a union or coupling 27 for the attachment of a pipe 28. The pipes 22 and 25 extend through one side of the casing 1 and serve to space the boiler from the wall of the casing, arrange the boiler in the center of the casing and also When the heater is set up, and used in connection with an oil tank 29 for heating or steaming oil, as it is called, in the oil tank, the pipe is connected to the tank, near the bottom thereof and by means of a tapered nipple 30 which taps the tank at the point where there is a body of water under the body 0f oil in the tank and the said nipple is proyided with a stop cock 31. The pipe 28 is connected to the oil tank at a point below the surface of the body of oil in the tank and is sufficiently long to extend nearly across the tank. The pipe 28 also has a stopcock 32. In installing the heater and connecting it to an oil tank care should be observed to have the bottom of the boiler in the heater somewhat lower than the body of the water in the bottom of the oil tank, in Vorder that the water may flow from the l lower portion of the oil tank to the boiler through the pipe 25.

In the operation of my improved heater, when the burners have been ignited, the flames from the burners are directed to the tubes of the boiler near the base of the latter so that the lower portions of the boiler tubes are heated by the direct application of flame thereto. Hence an intermittent circulation of water is maintained, therein, the water entering the boiler from the body of water in the oil tank through the return Vpipe 25 and becoming heated and'passing back from the upper end of the boiler through the flow pipe 2S into the body of oil in the oil tank, the resulting steam con* densing as it passes through the body of oil and descending to the body of water in the bottom of the oil tank and hence the oil c in the tank becomes heated and the water `in the bottom of the oil tank is utilized as a medium for heating the oil, more of the oil tion of my improved heater the water passes p oil in the tank.'

therethrough in a solid body and is heated, carrying all salt 4and foreign substances with it, through the heater and without having an opportunity to leave a deposit therein.

` The heat is supplied to the boiler near the base by the burners so that the waterin the base is heated to the boiling point but the upper portion of the boiler is not so highly heated. Hence the steam generated in the base of the boiler is condensed back to waterV in the upper portion of the boiler and the expansive force of the boiling water in they base of the boiler causes the water to pass from the upper portion of the boiler through the pipe 2S to the tank. A fresh supply of water from the tank then passes through the pipe 25 to the boiler, the action of the boiler being intermittent. Hence water is never vaporized in the boiler, the salt and foreign substances are not precipitated in the boiler but are carried back to the tank and the boiler is prevented from becoming clogged.

It will be observed that the boiler in the heater affords straight conduits for the waterv heated therein, thus greatly facilitating the passage and circulation of the water `therethrough and greatly hasten'ingand promoting the process of heating-'the Having thus described my invention, I claim Y A heater consisting of a pair of substantially triangular shaped headers, three vertically disposed tubes received in said headers, forwardly projecting nipples carried by said headers adapted to contact the inner circumference of said cylindrical member,

a pair of burners disposed within said cylindrical member and inV contact, each being in contact with two of said vertically disposed tubes, one of which is engaged in common by said burners whereby said burners prevent the contacting of said tubes and the inner circumference of said,

cylindrical member, said burners being spaced apart t0 permit one of said tubes passing' between the same, a pair of fuel supplying pipes tapped into said cylindrical member with their inner ends converging in said member, said burners connected to said tube pipes, and supported thereby,`and a connection between said pipe outside of said cylindrical member, and a circulating' pipe passing through said cylindrical member and received in said nipples whereby to form said vertical tubes. passing through or being directly heated by In testimony whereof I aiiiX my signature in presence `of two witnesses. y l
